A sample of oxygen gas (O2) applies 152 mmHg pressure on the walls of an 11.2 L steel container at 273 K. Assume ideal gas behavior. The ideal gas constant is 62.36 (L·mmHg)/(K·mol), and the molar mass of oxygen gas is 32 g/mol.

How many grams of oxygen gas are in the steel container?

16 g
1.6 g
32 g
3.2 g
